SPECIFICATION forming' part of Letters Patent No. 666,939, dated January29, 1901.

Application filed November 21, 1898. Serial NO- 6971058' (N0 111011813To all whom, t may concer-7c:

Be it known that I, ALEXANDER J. RU- DOLPH, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Machinesfor Forming Bottle-Necks, of which the following is a specication. i,

This invention relates to that class of machines which is used for thepurpose of forming the necks of glass bottles While the bottles are in aheated or duotile condition, and particularly to the tool for formingthe interior surface and lip.

The principal object ofthe invention is to provide a simple, economical,and eflcient tool for use in forming the interior surface of the neck ofa glass bottle and to assist in forming the lip thereof, and theinvention consists in the features, combinations, and details ofconstruction hereinafter described and claimed.

In the accompanying drawings, Figure 1- is a longitudinal sectional viewof my improved tool, taken on line l of Fig. 3; Fig. 2, a similar viewtaken on line 2 of Fig. 3, and Fig. 3 a transverse sectional view takenon line 3 of Fig. 2.

In the art to which this invention relates it is Well known that theinterior and ends of the bottle-necks are formed by forcing a plugtherein, rotating -such plug, and rotating a shoulder or face on theplug or some part of the machine against the lip of the bottle-neck. Theobjection to this style of mechanismY is that the material which formsthe bottleneck-usually glass in a ductile state--enters the seams,grain, or interstioes of the metal and accumulates or destroys theinterior surface of the bottle-neck and the lip thereof.

The principal object, therefore, of my invention is to provide a tool orplug which will remove these objections and which is adapted to be usedin connection with a hand-tool or a machine that is automatic orsemi-automatic in its nature, as will be more fully'hereinafterdescribed.

In constructing a tool in accordance with my improvements I make a blockA of the desired size, shape, and strength to hold the operative partsand in some instances, especially when it is desirable to use it inconnection with a machine, secure it to the spindle B of an operativemachine. This block is preferably provided with two horizontal rods C,which extend from the front end thereof and which are connected togetherby means of a tapered plug c at the front ends thereof. To reduce thefriction when forming the interior surface of the bottle-neck, thesehorizontal rods are provided with rotatable rolls D of cylindrical metaltubing, so that, as shown in Fig. 2, when the block is rotating therolls spread, size, and finish the interior` opening ofthe bottle-neckwithout destroying the surface. To form the lip of the bottleneck, theblock is further provided with two screw-pins or rods E and E', arrangedtransversely of the block and which form pivots upon which are mountedtransverse rolls e, adapted to bear against the bottle-lip, as shown inFig. l', and form the same Without destroying the surface thereof.

In illustrating and describing my invention I have illustrated anddescribed only the plug portion used for the purpose of forming theinterior surface 0f the bottle-neck and lip thereof and have left out ofconsideration other and Well-known machine parts used for forming theoutside of the bottle-neck, as such parts are well known to thoseskilled in the art.

While I have described my invention with more or less minuteness asregards form, specific uses, details of construction, and arrangement, Ido not desire to be limited thereto unduly or any more than is pointedoutin the claims. On the contrary, I contemplate all proper uses,changes in form, construction, and arrangement, the omission ofimmaterial elements, and the substitution of equivalents'ascircumstances may suggest or necessity render expedient.

I claiml. In a tool of the class described, the combination of two rollsradially arranged for forming the lip of a bottle-neck, two rollslongitudinally arranged to form the axial opening of ya bottle-neck, andan arrow-head C to form a support for the longitudinal rolls and assistin opening the bottle-neck, substantially as described.

2. In a tool of the class described, the com- IOO bination of two iiXedparallel rods, a roll mounted on each rod and a plug having a flat bodyand a tapered end entered onto and secured to the outer end of both rodsfor the rods, rolls and plug to enter and be rotated within abottle-neck and form the interior surface thereof, substantially asdescribed.

3. In a tool of the class described, the combination of two fixed rods,a roll mounted on each rod, a plug tapered at its end and entered ontoand secured to the outer end of both rods for the rods, rolls and plugto enter and be rotated within a bottle-neck and form the interiorsurface thereof, and rolls at right angles to the rod-rolls to engagethe end face or lip ot' the bottle and form the same into shape,substantially as described.

4. In a tool of the class described, lthe combination of a rotatablehead or block, two rods fixed in the head or block and projectingendwise therefrom, a roll rotatably mounted on each rod for the two rodsand their rolls to enter and be rotated by the rotation of the blockwit-hin the bottle-neck and form the interior surface thereof, and tworolls adjacent to the rod-rolls and rotatablymounted in the end face ofthe head or block to act and form the end face of the bottle-neck,substantially as described.

5. In a tool of the class described, the combin ation of a rotatablehead or block, two rods xed in the head or block and endwise projectingtherefrom, a roll mounted on each rod for the two rods and their rollsto enter and be rotated by the rotation of the head or block within abottle-neck and form the interior surface thereof, a roll on each sideof the rods at right angles to the rod-rolls, and a spindle for eachlateral roll, each spindle carried by the head or block to have therolls project from the end face of the block and form the end ofthebottle-neck, substantially as described.

ALEXANDER J. RUDOLPH.
